My husband and I have been seeing a light on the western horizon right at about 6pm every night for a while now. We traveled west on Hwy 72 and the light was not a plane or a tower light and I don't believe that it was a planet. It was yellow-orange in color and would move slightly from left to right. It wasn't blinking. As we got into Huntsville, the light was still there but not as bright because of the city lights. It had gone further down the horizon because it takes about 20 minutes to get to Huntsville. I know my planets and stars and I know that this isn't suppose to be where it is. What is it? An asteriod? It doesn't have a noticeable tail or anything. Just looks Venus but much brighter and not white but yellow-orange.
